Nicholas Suh, Alexander Carpenter, Sandra Ray, McKenzie Sorrell Investigation 11 Lab section BD Tuesday: 12:40-3:30 Reuben 9/19/07 How Much Sodium Bicarbonate is in the Mixture? Introduction In an ideal world chemists would always have access to pure substances to use in their experiments. However, this is not only costly, but frankly it is just not reality. It is important for everyone in any of the numerous fields that are associated with chemistry to make use of materials that contain impurities because this allows them to do the exact same experiment for a much lower cost. This can be very useful in the chemical manufacturing world because it can save the company a great deal of money on the raw materials while still producing the same amount of product. Experimental 1. Materials: 1.0 M H 2 SO 4 , Sulfuric acid 1.0 M Unknown Mixture 1.0 M HCl, Hydrochloric acid 1.0 M NaOH Sodium Hydroxide Sodium Chloride NaCl, pure Sodium Bicarbonate NaHCO3, pure 50 mL Beaker 100 mL Beaker Electric Balance Pipets Test tubes 2. Procedure: Before beginning this experiment, a preliminary experiment was conducted in order to achieve a greater understanding of the chemicals provided for this investigation. 1.0 M HCl, 1.0 M H 2 SO 4 , and 1.0 M NaOH were each mixed separately with pure NaCl in different test tubes and observed for reactions. The results were recorded. Then, 1.0 M HCl, 1.0 M H 2 SO 4 , and 1.0 M of NaOH were each mixed separately in different test tubes with pure NaHCO 3 and observed for reactions. The results were recorded. Based on the results of the preliminary investigation, two methods of determining the percent composition of Sodium Bicarbonate in the unknown mixture were developed. The primary method was carried out in three separate trials. First, 1.5 g of the unknown
